Someone named Michael wanting me to switch to their gas company, but I have researched all of them and I have the lowest priced by quite a bit, when I told him I would not switch he started yelling at me and wouldn't stop. Had to hang up on him, I will be calling the number back and filing a formal complaint against him and the company. I am on the do not call list and did not request any calls from them.  They are not exempt!!
